• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang ying) OR (wang jing)) yang li le sang min ((cong shu) OR (song thin)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) OR (wang jing)) yang li le sang min ((cong shu) or (song thin)) ;".
